BALANCE-IRON FOR MILLSTONES.

Specification of Letters Patent No. 18,74L1, dated December 1, 1857.

To all whom it may concern:

Be it known that I, JOSEPH H. GLOVER, of Skeggs Creek, in the county ofBarren and State of Kentucky, have invented a new and useful Improvementin Bails or Balance-Irons for Millstones; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the annexed drawings, making a part of thisspecification, in which- Figures 1 and 2, are vertical sections of myimprovement, the planes of section intersecting each other at rightangles. Fig. 3 is a detached view of the adjustable block.

Similar letters of reference indicate corresponding parts in the severalfigures.

This improvement consists in having an adjustable block arranged withinthe bail as and for the purposes hereinafter set forth.

To enable others skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

The bail or balance iron is formed of two legs (a) (a) connected attheir upper ends by a cross-bar or portion (1)) which has side-plates(0) attached to form a box A, as shown in Figs. 1 and 2. The legs (a)(a) and cross-bar (b) may all be formed of one bar of iron. The lowerends of the legs (a) (a) are bent outward horizontally a short distance,as shown at (5 (6 Fig. 1, and the upper surfaces of said projections arerounded and fitted in recesses made in the stone at the edge of its eye,see Fig. 1, in which the stone is shown in red. By having theprojections (Z3 (5 formed with rounded upper surfaces, the stone willrest or bear on the center of the projections, which, provided thecurves are regular, are in the same plane as the spindle, shown in red.Within the box A, a steel or metallic block B, is fitted or placed. Thisblock is somewhat smaller than the interior of the box, and a groove (0)is made horizontally around it. Through each side of the box A, a setscrew (d) passes; and the inner ends or points of these screws fit inthe groove and retain the block B in its proper place. The under surfaceof the block B has a center hole (6) made in it, to receive the point ofthe spindle. It will be seen that by adjusting the block B laterally bymeans of the set screws (cl), the stone may always be kept in aperfectly balanced state, without any trouble or expense; and when thecenter hole (0) becomes worn by use, the block B may be removed and anew one inserted in its place.

The ordinary bail, it will be understood is permanently secured withinthe eye of the stone, and when a new center hole is required, the bailis detached from the stone at considerable expense. The stone also isnow balanced by adding weights to it, at the light side. This plan is animperfect one, and is attended with considerable trouble.

I am aware that the bails of mill-stones have been provided with blockswhich were interposed between the point of the millspindle and theinterior surface of the bail; but to the best of my knowledge andbelief, it is new to render such blocks adjustable by means of screws,whereby the stone may at all times be readily balanced and a bet teroperation of the parts be thus secured, and the quality of the flourimproved.

In the patent of 'E. It. Benton, March 31st, 184cO, a block isinterposed between the point of the spindle and the bail; I disclaimeverything contained in the patent of said Benton which resembles myimprovement.

What I claim as my invention, and desire to secure by Letters-Patent, is

The block B, when made adjustable from the exterior of the bail by meansof screws (d), as and for the purposes herein set forth. 1
